DOMINIO BURKE, OF NEW YORK, N. Y.

WATER-CLOS ET BASIN.

SPECIFICATION forming part of Letters Patent No. 233,470, dated October 19, 1880.

Application filed March 19, 1880.

To all whom it may concern:

Be it known that I, DOMINIG BURKE, of New York city, State of New York, have invented certain new and useful Improvements in Water-Closet Basins or Hoppers, of which the following is a specification.

My invention aims to construct basins or hoppers for water-closets in a more durable and inexpensive manner than those heretofore used; and the essential feature of myinvention may be stated to consist in a water-closet basin orhopper composed of hydraulic cement, which forms a new and improved article of manufacture.

Figure 1 of the annexed drawings presents a vertical section of a hopper constructed according to my invention. Fig. 2 gives an inverted plan view of the hollow drenching-rim of the hopper detached.

The hoppers or basins maybe formed in any of the usual or adopted shapes or in any special shape desired, as my invention does not relate to the special form of the article. To produce the hoppers or basins according to my invention, I take a good quality of hydraulic cement-preferably the quality known as Portland cementand I mix the same with an equal quantity of sand in a mortar or other mixing vessel or machine, and, having prepared molds of suitable form and material to shape the said hoppers or basins, I fill the same with the said cement and then allow it to set or harden in the mold, so as to form the desired shape of basin or hopper. When the cement has hardened or set sufficiently I remove the casting from its mold and allow the hopper or basin thus cast to fully dry. When fully dry and hard the basins or hoppers may then be finished off by grinding or chiseling, if necessary, to impart any desired degree of smoothness thereto or to correct any defects of molding, if such occur. After these operations the hoppers or basins are ready for the market and are fit to be mounted or attached to the water-closets in the ordinary way, well known to plumbers, same as common crockery or iron basins or hoppers, and as thus formed they constitute a new and valuable article of trade for the described purpose. The advantages of hoppers or basins made in this way are that the material as well as the mode of (No model.)

manufacture is much less costly than that of the iron or crockeryhoppers heretofore made, and moreover my cement hopper or basin, while possessing great strength, is proof against the action of moisture, air, or alkalies to which its use exposes it, thus presenting an important advantage over iron, which rapidly deteriorates by rust, and of crockery orenamel, which is destroyed by the continued action of alkali.

I prefer to provide the upper edge of the basin or hopper with a hollow or grooved rim, B, through which the water is admitted to the hopper in an annular stream or series of jets, which rim is also preferably formed of h ydraulic cement molded in the same manner as the body of the hopper. This rim may have a flat or beveled shoulder, e, to rest upon the edge of the hopper, and a pendent edge, d, which projects within thehopper,with a groove, e, around its inner side to form an annular water-channel between the basin and the rim. The water may be admitted to this channel to flush the basin by a pipe extended through a hole, f, in the side of the basin, and it may discharge into the basin through a series of dents, g, in the pendent edge of the rim. By this construction of the rim it will be observed that while the water is admitted in the required manner the pendent edge of the rim rests at numerous points or intervals upon the interior of the basin and is thus well supported thereby. The rim may, however, be formed without the projecting and dented edge to bear upon the basin, and it may be supported at the desired points against the interior of the basin by dabs of cement placed at frequent intervals, and this cement may be so placed as to discharge the water into the basin at any desired point, or to distribute it evenly therein, as may be desired. The rim is cemented, by a suitable water-ti ght cement,to the basin around the top edge, so as to prevent any escape of water outward.

Instead of employing a mixture of cement and sand, as is first described, I may use cement alone, or cement mixed with slag or with ground cinders, ground brick, or similar material, as will be readily understood.

Instead of making the drenching-rim of the hopper as well as the body thereof of hydraulic cement, I may use a rim of crockery or metal shape or design of the article required, with or without a hollow rim, substantially as herein set forth.

2. A hollow rim for water-closet. basins or 15 hoppers formed of hydraulic cement, substantially as herein shown and described.
